    The Financial Crisis and the Systemic Failure of the Economics Profession (2009)
    In:  Critical review: a journal of politics and society
    Details
    Publication Date: 2023-07-18
    Description: Economists not only failed to anticipate the financial crisis; they may have contributed to it — with risk and derivatives models that, through spurious precision and untested theoretical assumptions, encouraged policy makers and market participants to see more stability and risk sharing than was actually present. Moreover, once the crisis occurred, it was met with incomprehension by most economists because of models that, on the one hand, downplay the possibility that economic actors may exhibit highly interactive behavior; and, on the other, assume that any homogeneity will involve economic actors sharing the economist’s own putatively correct model of the economy, so that error can stem only from an exogenous shock. The financial crisis presents both an ethical and an intellectual challenge to economics, and an opportunity to reform its study by grounding it more solidly in reality.

    Desert Soils in Lower Wadi Howar (2007)
    Leidorf
    Details
    Publication Date: 2021-03-29
    Description: The analysis of desert soils near archaeological sites allowed new insights in the environmental and living conditions of the early inhabitants of the Wadi Howar (NW Sudan) and their interactions with their environment. It also provided us with more information about the soil genesis in arid regions. Further studies should concentrate on dating the described indicators of a more humid climate in the eastern Sahara during the Holocene.

    The difference between pollen types and plant taxa: a plea for clarity and scientific freedom (2007)
    Geozon Science Media
    Details
    Publication Date: 2024-02-28
    Description: Dieser Artikel diskutiert den Charakter von Pollentypen. Wir argumentieren, dass Pollentypen und Pflanzentaxa komplett unterschiedliche Entitäten (morphologische bzw. taxonomische) sind, und deswegen unterschiedlich behandelt und dargestellt werden sollten. Allgemeine Probleme der konventionellen Nomenklatur von Pollentypen werden anhand von Beispielen aus der europäischen palynologischen Praxis illustriert. Wir plädieren für Deutlichkeit in der Nomenklatur von Pollentypen und für die wissenschaftliche Freiheit, ‘unkonventionelle‘ Methoden zu benutzen, um Verwirrung zu vermeiden.

    Thermal properties of gas hydrate bearing sediments and effects of phase transitions on the transport of heat deduced from temperature logging at Mallik, NWT, Canada (2005)
    GFZ, Helmholtz-Zentrum
    Details
    Publication Date: 2023-08-29
    Description: Detailed knowledge about the thermal properties of rocks containing gas hydrate is required in order to quantify processes involving the formation and decomposition of gas hydrate in nature. This work investigates the influence of methane hydrate on the transport of heat in hydrate-bearing rocks. Both the thermal conductivity of gashydrate bearing sediments and the thermal effects of phase transitions are analyzed. In the framework of the Mallik 2002 program three wells penetrating a continental gas hydrate occurrence under permafrost were successfully equipped with permanent fiberoptic distributed temperature sensing cables. Temperature data were collected over a period of 21 months after completion of the wells. The analysis of the disturbed well temperatures after drilling revealed a strong effect of phase transitions on temperature changes. For the first time, the effects of induced temperature changes within a gas hydrate deposit were monitored in-situ. The resulting temperature gradient anomalies could be successfully utilized to determine the base of the gas hydrate occurrences and the permafrost layer at about 1103-1104±3.5 m and 599-604±3.5 m below ground level respectively. At the end of the 21-month observation period, the well temperature returned close to equilibrium with the formation temperature. At the base of the gas hydrate occurrences a temperature of 12.3 ◦C was measured, which is about 0.7 K below the stability temperature predicted by thermodynamic calculations considering a pressure gradient of 10.12 kPa m〈sup〉−1〈/sup〉 and a sea-water salinity of 35 ppt. Under the stated conditions, the base of the stability zone of methane hydrate at Mallik would lie at about 1140 m below ground level. Thermal conductivity profiles were calculated from the geothermal data as well as from a petrophysical model derived from the available logging data and application of mixing-law models. The results indicate, that variations of thermal conductivity are mainly lithologically controlled with a minor influence from hydrate saturation. The results of the geometric mean model showed the best agreement to the thermal conductivity profiles derived from geothermal data. Average thermal conductivity values of the hydrate-bearing intervals range between 2.35 W m〈sup〉−1〈/sup〉 K〈sup〉−1〈/sup〉 and 2.77 W m〈sup〉−1〈/sup〉 K〈sup〉−1〈/sup〉 . A simplified numerical model of conductive heat flow was set up in order to assess the temperature effect of phase transitions within the gas hydrate bearing strata. Within the model the mobilization of latent heat during the phase transition was considered (enthalpy method), taking into account the stability conditions for methane hydrate at Mallik (pressure, temperature, pore fluid and gas phase composition) as well as effects of hydrate decomposition on the thermal rock properties. The modelling results indicate, that the regeneration of hydrate after the recovery of stability conditions is inhibited.
